If you ask 100 people and 60 say they are students, then you would assume that 60/100 people in town as a whole are students.  To estimate the non-student population, you would infer that the other 40 are not students, thus making the non-student to student ratio 40:60 or 2:3 when simplified.  This means that for every 2 non-students, there are 3 students.  If we multiply 2000 by this 2:3 ratio, we would see that 2/3*2000 = the non-student population.The non-student population is estimated at 1,333.

After college you start a job earning $40000 a year. You get a 6% raise each year. a) How much will you earn in year 2?
Elodia [21]
The answer to Part a is $44,800. I did this by 40000*2*3/50 which comes out to 4,800 you add that to your beginning worth, 40,000. Part b is as follows; 9,600 which comes out to be $49,600. Replace the 2 in the original equation to be 40,000*4*3/50. The number '2' and '4' represent the years, and the 3/50 is equal to 6%. 6% in math terms is 3/50. The answer to part c is as follows; 40000*10*3/50 which comes out to be 24,000 so your final answer for part c is: $64,000 I hope this helped! Let me know if you need more work shown, and I'll add more! :)

The mean is the average value of the numbers given in the series

The mode is the number that is appears more than any other number given in the series

Step-by-step explanation:

Given challenge is make a list of 5 numbers

The list of 5 number is = 8,10,12,15,15

Mean value = (8+10+12+15+15)/5 =60/5 = 12

so required mean is 12 has been computed

Mode = 15 ( the number 12 is appeared in two times 8,10,12,15,15)
